Two circles are drawn inside a big circle of diameter 24 cm. The
diameter of the two circles are 1/3 and 2/3 of the diameter of the big
circle as shown in the adjoining figure. Find the ratio of the areas of the shaded part to the unshaded part of the circle.

Answer:the area of a big inside circle =pirsq
d=1/2r
r=12
22/7*12*12= 452.16 area of big circle.
the diameters of small two circle 1/3 and 2/3 respectively
1/3+2/3=24
R=12
1/3*12= R1 =4
2/3*12 = R2=8
area of two small circle =pi(r2+r2)
22/7 (16+64)= 251.2
we need to find out shaded area = area of big circle - areas of two small circle
452.16-251.2= 200.96 ans
